Wavelength-Dependent Extinction and Grain Sizes in Dippers
Michael L. Sitko, Ray W. Russell, Zachary C. Long +8
We have examined inter-night variability of K2-discovered Dippers that are not close to being viewed edge-on, as determined from previously-reported ALMA images, using the SpeX spe…
RR Lyrae mid-infrared Period-Luminosity-Metallicity and Period-Wesenheit-Metallicity relations based on Gaia DR3 parallaxes
Joseph P. Mullen, Massimo Marengo, Clara E. Martínez-Vázquez +8
We present new empirical infrared Period-Luminosity-Metallicity (PLZ) and Period-Wesenheit-Metallicity (PWZ) relations for RR Lyrae based on the latest Gaia EDR3 parallaxes. The re…
Relation of Observable Stellar Parameters to Mass-Loss Rate of AGB Stars in the LMC
Henry A. Prager, Lee Anne Willson, Massimo Marengo +1
Using the Riebel et al. (2012) data set for 6,889 pulsating AGB stars in the LMC, we have derived formulae for mass-loss rate as a function of luminosity and pulsation period or lu…
On the dwarf irregular galaxy NGC 6822. I. Young, intermediate and old stellar populations
Maria Tantalo, Massimo Dall'Ora, Giuseppe Bono +13
We present accurate and deep multi-band () photometry of the Local Group dwarf irregular galaxy NGC 6822. The images were collected with wide field cameras at 2m/4m- (INT,CT…
X-rays in Cepheids: Identifying Low-Mass Companions of Intermediate-Mass Stars
Nancy Remage Evans, Scott Engle, Ignazio Pillitteri +12
X-ray observations have been made of a sample of 20 classical Cepheids, including two new observations (Polaris and {\it l} Car) reported here. The occurrence of X-ray flux around…
Metallicity of Galactic RR Lyrae from Optical and Infrared Light Curves: II. Period-Fourier-Metallicity Relations for First Overtone RR Lyrae
Joseph P. Mullen, Massimo Marengo, Clara E. Martínez-Vázquez +11
We present new period--[Fe/H] relations for first overtone RRL stars (RRc), calibrated over a broad range of metallicities () utilizing the lar…
